PINCH-IBAR.

To all whom it may concern:

Be it known that I, EDUARD SorIoLLE, engineer, a subject of the German Emperor, and residing at 104 Sternstrasse, Neuss-onthe-Rhine, Germany, have invented certain new and useful Improvements in Pinch- Bars, of which the following is a statement;

The present invention relates to an arrangement for moving wagons running on rails.

The new arrangement difiers from other known devices of this kind in that it does not comprise any movable parts, which might bend or get slack in working in consequence of the heavy strain.

The present invention is exemplified in the accompanying drawing. a

Figure 1 is a View showing the pinch bar in use. Fig. 2 is an enlarged view of its operative end. Fig. Si a top view of its end and Fig. i is a section on the line AB in Fig. 2. i I

The strong bar a, made of steel,has at one end a broad point band at the other end a stud at, on which a long'pieceof tube f is fitted. Close next to the point 6 two flat bosses g are forged, and a dovetail groove h is cut into the underside: of the bar between these bosses 9. Into this groove is driven with a tight fit a triangular wedge 2'. This wedge i is prevented from leaving'its groove by two plates of a peculiar curved shape 76, which are fitted fiat against the bosses g and are held tightly pressed'against the latter by means of a screw boltm/ At their upper ends these plates 70 have inwardly turned noses at, which engage over the edge of the bosses g and thereby prevent the plates 70 from turning. g a

The pinch bar is placed with the edge of the wedge a on the top of the rail, and the Specification of Letters Patent.

point 6 is inserted between the wheel of the wagon and the raiL, Then this point is raised by the tube being pressed downward," so that the, wheel isforced forward. The sharp edge of the wedge prevents the pinch bar from gliding along the rail.

When the pinch bar is to be used for around a right angle, so that it assumes the posltlon indicated by the dot-and-dash lines in Fig. 2, and the screw m is tightened again. Also in this position the plate Z: is held by the nose n engaging over the edge of the boss 9, and the other plate is inserted into the groove of the rail, or into the groove intended for receiving the wheel flange. The operation of the pinch bar is then the same as hereinbefore described.

The pinch bar forming thesubject of the present invention may, thus, also be used with any type of rail and with switches,

and its slipping on the rail during the operation is reliably prevented.

I claim:

A pinch bar consisting of a bar tapered fiat at one end and having at its otherend a long tube fitted to it, in the undersideof said bar a dovetail groove, in said dovetail groove a long prismatic wedge, two plates held against bosses at the sides of said bar H by a screw bolt and adapted to hold said wedge in position.

Intestimony whereof I have hereto afiixed my signature in'the presence of two subscribing witnesses. i
